Building on a SLOPE? Caveats- WHY Slopes Fail

Asheville Real Estate Journal:
Asheville Area Mountain Home BuildersWHY Slopes Fail and Maps That Show Where ThAsheville Area Mountain Rangeey Might 

BUILDING IN THE MOUNTAINS? Consider this first:  Land Suitability.  Site and Building Design.  Site Resource Assessment  and,  in the mountains, engaging a team of local experts prior to investing in the land and/or building site: a geo technical engineer, a structural engineer, a landscape architect, an architect, a hydrologist, a soil scientist who understand the idiosyncrasies of mountain construction.   ( Photo shows Asheville Area Mountain Range- Would YOU Build Here?)

To make sure the home is solid on the site,one LEED ®Certified General Contractor here in the Asheville area expects buyers to invest $30,000 to $40,000 just on the foundation of the home.

Reminder: It takes less rainfall to trigger a debris flow on a modified slope (with evidence of prior instability) than on an unmodified slope. 

Here in the Ashevillearea mountains, Rick Wooten and the North Carolina Geological Survey Staff of the North Carolina Department of Environment and Natural Resources  have just introduced the Landslide Hazard Map for Asheville and the surrounding towns in Buncombe County, NC.  In addition, they informed an attentive audience in this presentation:

NOTE: Landslide Hazard Maps help to identify potential hazard areas, but do NOT substitute for site-specific investigation.
